IMPROVED CARPET-SWEEPER.

Specification forming part of Letters Patent No. 90,2 l1, dated May 18,1869.

To all whom t may concern Y Be it known that I, Oris H. WEED, of Boston,Suffolk county, in the State of Massachusetts, have invented a new andImproved Carpet-Sweeper, of which the following is a full, clear, andeXact description, reference being had to the accompanying drawings,making a part of this specification, in which- Figure lis aperspectiveview of the sweeper. Fig. 2 is an end view, with the drivingwheelsexposed. Fig. 3 is a view of the adjustable bearings.

My invention has for its object to provide a carpet-sweeper having'sutieient power in the drivin g-wheels to secure the constant and easyrevolution of the brush whether the sweeper be moved backward orforward.

Sweepers have heretofore been made with only one drivin g-wheel, workingin connection with a wheel on the brush-shaft. This arrangement not onlyfailed to give sufcient propelling-power, but it necessitated the use oftrucks or casters on the other corner, to keep the box containing1 thebrush level.

Sweepers have also been made with three pulleys, operating with a rubberband; and to avoid the objection to this mode of gearing,

the rubber band extending around the three pulleys was changed to arubber band around the two outer pulleys, and a rough cog-wheel placedon the end of the brush-shaft, as shown inthe patentof G. and II.Purrington, granted January 1, 1867.

It is evident, however, that the frequent use of a sweeper would soondestroy the rubber bands or render them inoperative.

provided with cogs which it into cogs on the v wheel B, attached to thebrush-shaft.

In the place ofthe cog-wheel B a rubber' gear-wheel may be used, inorder to make the operations of the sweeper noiseless.

The driving-wheels A A rest in the horizontal adjustable bearings D D,with their slots a a, and the brush-shaft, with its gearwheel, restsupon the vertical adjustable bearings G G, with its slots c e.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination and arrangement ofthe drivin g-wheels A A with theireogs, in combination with the cog-wheel B and adjustable bearings D Dand G G, substantially as and for the purpose described.
